Installer and User Manual
Model C365T21
Ver4.00 Jan 2018
Description
The Comfort365 thermostat controls heating, cooling and airflow to the sleeping and living areas. The thermostat is installed in the living area, a temperature sensor is installed in the bedroom area and two modulating dampers are installed to control the airflow to the living and sleeping space.
The C365 thermostat monitors the temperature at the sensor and the temperature at the thermostat every 2 minutes during heating and cooling calls. If the temperatures are different, the Comfort365 automatically adjusts the modulating dampers 2% so that more airflow is directed to the space that needs it for a uniformly comfortable home.
The energy saving nighttime airflow control option uses the temperature sensor in the sleeping space to control heating and cooling calls and directs more airflow to the upstairs sleeping space while decreasing the airflow to unoccupied living space.
The user can manually adjust airflow on occasions when more airflow is needed in the bedroom space or living space.
SYSTEM MODES Off, Heat, Cool, Auto
FAN MODES Auto or Continuous
THERMOSTAT MODES Hold, Schedule or Vacant mode.
PROGRAMS PER DAY Morning, Daytime, Evening and Night.
PROGRAM FORMAT Weekdays and weekend– 5/2.
TEMPERATURE OVERRIDE Temperature is held for 3 hours when adjusted in Schedule mode.
AIRFLOW CONTROL Airflow control can be turned off using
Option 17. The thermostat will operate as a typical thermostat.
AIRFLOW LIMITS Maximum airflow limits in heating and cooling can be set during installation.

NIGHTTIME OPERATION The C365 thermostat uses the temperature sensor to control heating and cooling calls and directs more airflow to the sleeping area.
If bedrooms are located downstairs, consider turning off the Nighttime Airflow
Control option off.
COMPATIBLE EQUIPMENT Gas/electric equipment with 2stage heating and 1-stage cooling or 1-stage heating and 2stage cooling and heat pumps with 2-stage heating and 2stage cooling.
TEMPERATURE SENSOR One TS510W sensor or two
TS520W temperature sensors can be used in the sleeping area.
MODULATING DAMPERS Round or rectangular dampers using the A80MT actuator and up to 1 inch static pressure.
POWER Operates on 24VAC from the HVAC equipment using the R and C wires.

Disabling Airflow Control Turn Airflow Control Off using Option 17. The thermostat will control the system just like any other thermostat. Dampers fully open, nighttime airflow options are disabled and airflow is no longer displayed on the thermostat
User Airflow Control enables the user to control the airflow rather than the thermostat automatically controlling the airflow. Installer must enable Option 18 and the user must turn off automatic airflow in the
User Options. The Nighttime Airflow Control is still enabled, but can be turned off using User Options.
i
Nighttime Airflow Control is defaulted to On. If bedrooms are located downstairs, consider turning off the
Nighttime Airflow Option using the User Options.

READ THESE INSTRUCTIONS CAREFULLY
AND COMPLETELY BEFORE PROCEEDING WITH INSTALLATION.
!
Turn off all power to the HVAC system before wiring or installing Comfort365 components.
SEPARATE THE C365 SUBBASE
Place a slotted screwdiriver in the slots as shown and rotate to remove subbase from the C365 housing.
INSTALL TWO AA BATTERIES
The batteries power the clock when 24VAC power is lost.
Slide the battery cover downward and install the two
AA batteries as shown.
ATTACH THE SUBBASE TO THE WALL
Attach the subbase to an interior wall and about 5-feet above the floor as shown using the screws and wall anchors supplied.
The wires to the dampers, HVAC equipment and the temperature sensor pass through the opening between the terminals.

INSTALL SLEEPING AND LIVING AREA DAMPERS
Install an R80CT damper in the duct supplying air to the sleeping area and wire the terminals to the corresponding terminals on the C365T21. Install a second R80CT damper in the duct supplying air to the living area and wire it to the
C365T21. Each damper uses 2.4VA of power.
i
Ensure that damper installation does not cause obstruction to the damper blade.
When two or more dampers are required to define the sleeping or living area, the dampers may be wired in parallel. LEDS on the damper actuator indicate when the damper is fully open
(green) or fully closed (red).

ATTENTION HOMEOWNER
Your Comfort365 thermostat includes several features to optimize your comfort, including:
Nighttime Airflow Control.
At night, the sensor in the sleeping space is used to control heating and cooling calls and directs more airflow to the sleeping space and less to the unoccupied living space.
In addition, the airflow to the sleeping space can be adjusted for more comfort. This option is defaulted to On. See User Menu Option 3 for more information on Nighttime Airflow Control.
Airflow Override On occasion you may want to direct more airflow to the living or sleeping space. Simply touch the airflow area and use the UP and DOWN keys to adjust the airflow to sleeping or living space.
After 3 hours, the airflow returns to automatic operation. See Using
Your Comfort365 Thermostat, Option 8 and 9 for more information.
